To understand more about the kinds of tweets attracting high levels of abuse, we considered several approaches for ranking them. Ranking tweets by the most replies will surface prominent individuals, but perhaps not always polarising individuals or viewpoints. We decided on an initial criterion that a tweet had to have received 8% or more abusive replies, which is nearly twice the average level of abuse noted by [1]}, [2]}, [3]}. In addition, to filter out tweets that were attracting just a handful of abusive replies, we examined tweets that received at least 20 abusive replies.
